Letters Patent No. 109,571,

dated November 29, 1870.

The Schedule referred to ixirthese Letter To all whom it may concern:

Be it known that I, JOHN IVlAUsTIX, ot' Ilaqncmine, in the parish of Iberville and State of Louisiana, have invented a new and useful Improvement in Apparatus for Clarifying Cane-juice with Sulphur-ous- Acid Gas; and I do hereby declare that the following, is a full, clear, and exact description.thereof, which will enable others 'skilled in the art to inake and use the same, reference being had to the accompanying drawing fol-'ming part of this specification, in which- Figure l is a vertical section of my improved apparatus, taken through the line n. a', fig. 2. A

Figure 2 is a detail horizontal section ot' the same, taken through the line y y, iig. 1.

Similar' letters of reference indicate corrcspoluling parts.

My invention has for its object to furnish an improved apparatus for bleaching, clarifying, and' otherwise affecting cane-juice and other liquids by the application ot" sulphurous-acid gas or other gases, which shall be simple in construction and-effective in opera-A tion; and

It consists in thc construction and combination of various parts of the' apparatus, as hereinafter more fully described.

A is a tank of anydesired or convenient size, which I prefer to niake of wooden vstares with iron hoops.

The tank A is supported at aconvenient height y,hy short post-s I5.

C is a spindle passing up through the center ofthe tank A, and the lower end of which revolves in a step, I), as shown in iig. I.

The spindle O has a pulley, c', attac/hed to it, to rcceive the belt by which the said spindle is revolved, and which may be driven by any convenienty power.v

Eis the top or cover of the tank A, which is iliade with an opening in its center, through which the canejuice and sulphnrous-acid gas are introduced into the tank A.

.io the cover E issecured a close trough or pipe, F, having a hole in its bottoni corresponding witlrt-heholc through the cover E. One part or end of the trough I` receives the cane-juice and conducts it into the tank A. This part of tire trough Is should 'be provided with a hinged or swinging gate, as indicated in dot-ted juice, andjmay prevent the escape ofthe gas.

The other part or end ofthe trough lt receives the gas from the retort or furnace, and conducts it into the tank A through the saine openingr with the canejnicc. In thc top of the trough F, directly over the opening leading into the tank A, is formed an opening, closed with a door, for convenience inl cleaning out the .thoroughl y mixed.

s Parent and making part of the same.

(irvis a drum, securely attached to the upper end of opening in its centerl directly beneath and corresponding with the opening-in the top E ofthe tank A.

The top or cover E 'of the tank A, around its opening is provided with a downwardly-projeeting angc, which overlaps an upwardly-projecting flange attached to the top oi' the drum G around its opening, to guide thc-juice and gas into the said drum G.

The top and hott-01net' the drum G are connected by radial partitions extending from the outer edge of the said drum to the hole in the center of its top, a-s shown in iig. 1, and in dotted lines in iig. 2.

ly this construction, as the juice and gas ow into the rapidiy-rcvolving drum G, they are thrown ont around the sides ot'l the tank A by' centrifugal force, and are thoroughly intel-mingled. 4

The mingled juice and gas from the drum Gr falls upon the partition II, that divides the tank A into two compartments, and the iniddlc part of which inclines slightly downward, and hasa hole formed through its center, through which the spindle O passes, and through which 4the mingled juice and gas flows to thc drum l'.

'Ihe drum I is securely attached to the spindle C, so as to be carried around by and with` the said spindle (l in its revolution. rIhe ldrum I is made in the forni ot'a conical or hemispherical plate, having radial flanges or ribs attached to its upperor convex side, as

shown in l and 2, vso that as the mingled juice and'gas ilows upon it from the partition H, t-hey may be again thrown outward hycentrit'ugal force and more Ifhe mingled juice and gas from the drum I falls upon the bottom J of the tank A, the middle part ot' which is inclined downward or concaved, and has a hole or opening formed in its center, through whichv the spindle C passes, and through which the-mingled juice and gas tlows into the basin K, placed beneath and secured tc the bottom .I and from which the juice and escaping gas tlowsout through the pipe oi" trough L, which should be provided with a hinged or pivoted gate opened by the outtlowing liquid.

'Ihe basin K is made with an open pipe, It', in its center, tln'oughwhich the spindle U passes, and which prevents any ofthe juice from escaping around said spindle.

Havingthus describedmy invention,

I claim as new andkdesire to secure Patent- 1. rIhe druin G, constructed as described, in conibination with the spindle O and tank A, having openby Letters ings in the centers of its top E and partition or botl tom H, for the ingress and egress ofthe juice and gas, substantially as herein shown and described, and .for the purpose set lorth..

2. The drum I, constructed as described, in eelnbination with the spindle G, drum G, and tank A, hm'- ing epeningsin the centers ei' its 'top E, partition H, and bottom J, for ille passage of the juice and gas,

substantially as herein shown and described, aud for' the purpose set forth.

3. The basnrli, constructed with a central open pipe, L", and discharge trough or spout L, in combi- :natiou with the 'spindle C, drums G and I, and tank '.A, haring openings iu the eeuters'of its top E, partition H, and betteln J,fi.)r the passage oi' the juice and gas, substantially as herein shown and described, and for the purpose set; forth.
